Dodecylamine

CAS: 124-22-1

Overview

Dodecylamine (CAS 124-22-1 ), also known as Laurylamine, is a long-chain primary amine used across surfactant manufacturing, polymer processing, and surface treatment applications. Its twelve-carbon chain structure positions it as a building block for cationic and amphoteric surfactants.

This chemical serves as a vital component in the production of corrosion inhibitors and flotation agents. In mineral processing, it functions as a collector agent in froth flotation, selectively binding to silica and oxide mineral surfaces to enable ore separation.

Polymer formulators use it as a curing agent and crosslinker in epoxy systems, improving adhesion and mechanical performance in coatings and adhesives. Personal care manufacturers incorporate it as an intermediate in the synthesis of quaternary ammonium compounds.

These compounds and amine oxides are frequently used in conditioning and cleansing formulations. In plastics, it acts as a surface modifier for fillers and pigments, improving dispersion and compatibility within polymer matrices during the manufacturing process.

Dodecylamine is supplied as a solid flake or liquid melt, depending on temperature and packaging format. Standard commercial grades include technical-grade material, with purity levels typically ranging from 95% to 99%+ to meet industrial requirements.

Bulk quantities are available in drums and IBCs, with some suppliers offering flaked product for easier handling in solid-state processing. The material is handled according to strict safety protocols to ensure stability and performance in diverse chemical environments.
